Police have identified Jason Razzino as the shooter in an armed standoff at the Cedar Glen Apartments in Norwich on Monday and Tuesday in which a Norwich police officer was shot.

Police found Razzino, 30, dead in his apartment's bathroom of a single self-inflicted gunshot wound, according to a news release from state police spokesman Lt. J. Paul Vance.

During an exchange of gunfire at about 4:45 p.m., Norwich police officer Jonathan Ley was hit by four shots and critically wounded. His condition has been upgraded to serious Tuesday morning, said Mark DeAntonio, a spokesman at Yale-New Haven Hospital.

Razzino fired at Norwich officers with a rifle and handgun, police said.

Norwich police have let residents return to Buildings A, B and C of the apartments. Building D, where Razzino lived in a third-floor apartment, is still off-limits.
